Specification of Letters Patent.

Patented Feb. 7, .19.22.

Application filed December 13, 19719. Serial No. 344,576.

To all whom t may concern Beit known that we, RICHARD A. PHELAN and HAROLD A. 'VEGUELIR citizens of the United States, and residing in the city of St. Louis and State of Missouri, have invented certain new and useful Improvements fumes from iodine crystals to be used for chemical purposes by changing the almost insoluble iodine crystals into iodine fumes which fumes are freely soluble in alcohol, or oils without the addition of other chemicals.

'A further object of the invention is to provide a device for generating non irritant fumes from iodine crystals to be used internally in treating armucous membrane, such as the ear, nose and throat and for external purposes in treating open wounds, extensive burns and the like.

A further object of our present invention is to provide a transparent device of this class made of glass, which will readily generate fumes from iodine crystals, or other volatile chemicals when heat is applied to the device, which will permit the fumes to be seen while being generated and to permit the generated fumes to be visible until they have been discharged. f

A further object of the invention is'the provision of means to receive the crystals, while being generated into fumes, and prevent dense accumulations from being driven out of the device with the fumes.

A. still further object of the invention is to provide an all glass generator, which consists of a minimum number of parts, that can be readily assembled and disassembled, convenient and practical to handle and operate and which will be highly efficient for the purposes intended.

lVith the above and other objects in view, the invention consists in certain novel features of construction, arrangement and comand finally pointed out in the claim hereto appended.

Referring to the accompanying forming a part of this specification wherein like characters of reference denote similar parts throughout the several views:

Fig. 1,. is va longitudinal sectional view of a fume generator constructed in accordance with our invention.

Fig. 2, is a sectionalview, partly in sid elevation of the medicament' retainer and fume generating section of the device.

Fig. 3,'is a sectional view, partlyin side eleva-tion of the fume filtering section carried atthe discharge end of the :fumegenerating section.

Fig. 4, isa sideY elevation, partly Ain fsec-4 tion of the fume :discharging or 'nozzle lsection of the device.

Referring to the drawings, 'the reference character 1 indicates a suitable .rubber bulb having a nipple 2 provided with an air discharge passage. The opposite end of the bulb is provided withan air inlet opening 4 provided with a suitablecheck valve 5.

6 indicates a .glass fume generating .tube section having a contracted tubular neck 'T at oneend. A suitable hose connection 31 connects the nipple 2 with-the .neck 7 of the fume generating tube 6.- The fume gener-V ating tube is provided with anenlarged-section 8 to hold the'iodine or. other medical crystals designated 9. 'The fume generating tube isprovided with a contracted .tubular neck 10V which is coveredwith asuitable packing 11. v f Y 5 12 Vindicates a glass tubular member having a contracted neck portion 1-3. The neck portion of the tubular member 12 is provided and encircled with a suitable packing 14. The neck 13 and packing 14 are inserted into the contracted tubular neck 10 of the fume ygenerating tube s0 that the neck will extend slightly into the generating chamber 15 of the fume generating tube 6, as clearly shown in Fig. 1. A suitable filler, such as cotton 16 to act as a fume strainer or filter, is inserted into the tubular member 12.

drawings 17 indicates a glass tubular nozzle section which has telescopic connection with the acking 11 which covers the contracted tubullar neck portion of the fume generator tube 6. The tubular nozzle section 17 is contracted as at 18 and provided at its outer or discharge end. with B suitably shaped preferably tapered nozzle end 19 having a fume discharge opening 20. The tubular member 12 is positioned with the tubular nozzle `member 17 when the device is as' sembled, as clearly shown in Fig. 1.

21 indicates a suitable alcohol lamp or other device which is capable of producing a small flame designated 22 for heating the fume generating tube 6 to heat the crystals 9 so they will throw off fumes, which fumes are to be discharged from the generating chamber through the straining or filtering tube and finally through the nozzle member of the device by pressing on the bulb l to force@l air through the device for discharging the generated fumes, asis manifest. The operation `of the device, after it has been assembled,as shown in Fig. 1, is as follows:

The chemical crystals V9 are placed. into the generating tube before the fume strainer section and nozzle are assembled. The crys- .tals 9; are adapted to lie in the bottom of the enlarged section 8 of the tube' 6. The device` lsthen passed horizontally over the flame 22v until the fumes generated from the crystals gain the desired strength. The bulb l-is then pressed together and the fumes through this pressing operation of the bulb arel discharged through the discharge opening 2() of the nozzle member and directed upon or into the effected tissues, or inhaled.

It is evident from the foregoing description .that the fume generating and Vdischarging device herein described and illustrated is simple in operation, that the`color`and density of the fume generated can be easily controlled owing to the fact that the' entire device being made from glass the fumes are visible at all times until discharged and further that owing to thev enlarged section 8 of thel generating tube and the axially disposed strainer section there can be no ash discharged withthe fumes out of the dischargeopeningfQO. It will befurther observed that there being no metal parts with which the generated fumes come in contact that no foreign chemical action can take place so that only the chemically pure generu ated fumes'can be discharged from the device which are always ,under control as to We d0 not wish to be understood as having y limited ourselves to the details of construction shown and described, but desireA to have it understood that the invention we have shown in the drawings is merely illustrative, as it is manifest that various minor changes may be made in the exact construction Vand particular arrangement` of parts without departing from the spirit of our invention, hence we reserve the right to make any such changes or modifications as may fairly fall within ythe scope of the appended claim when lfairly construed.

What we claim is: In combination, a transparent` generator tube having an enlarged body portion to hold crystals to be generated into fumes by applying heat to the generator tube, a transparent tubular member mounted in one end of the generator tube and extending into the generating chamber thereof, filtering means carried by the transparent tubular member, a transparent tubular nozzle having a discharge opening in one end, said nozzle having connection at one -end with one .end of said generator tube and a Yrubber air'bulb having connection with the opposite end of said generator tube for discharging the generated fumes by compressing the bulb with` the fingers.
